Still Standing is an achievement that can be unlocked on the most recent iOS and Android versions of Plants vs. Zombies. To earn it, the player must complete all five finite Last Stand puzzles. Before the player can unlock it, they will need to have $100,000 in order to purchase the Last Stand game pack.
The name is a reference to the Puzzle Mode's name, Last Stand, by stating that the player is "still standing" for comedic effect. In addition, the Achievement's icon shows a very battered and beaten up Wall-nut, referencing the fact that a Wall-nut is on the icon for the Last Stand Puzzle Mode.
